2.4708 has a very good warm and cold forming characteristics. The preferred method of shaping is cold forming. Hot forming is carried out in the temperature range from 1,230 to 954 °C. The temperature range between 593 and 816 °C should be passed as rapidly as possible,it is widely used in Reaction vessels
Heat exchangers,Valves,Pumps,Piping,Storage tanks
Melting way of 2.4708 forged bars is as follows:
Alloy shall be multiple melted using consumable electrode practice in the remelt cycle or shall be induction melted under vacuum.If consumable electrode remelting is not performed in vacuum electrodes which have been produced by vacuum induction melting shall be used for remelting

Criteria stipulated in SEP 1923 quality class 2 b shall be applied with following modification:EE(single echo)and VE(numerous single echoes)without extension ≥2mm KSR are not permitted Defects above the recording limit shall be marked and it shall be ensured that these 1.4906 forging flat bars are not included in the lot delivered.
An inspection certificate 3.1 according EN 10204 of our 2.4708 forged bars should have following
purchase order, item, serial n°, drawing number and number of the technical purchasing
specification
material designation
heat n° and heat analysis
method of melting
manufacturing procedure
heat treatment: cooling method (rates and mean of cooling) and measured temperatures.
All heat treatment conditions have to be quoted in a graphic temperature against time
sequence (including all re-heat-treatments). Reports including only average holding
temperatures and times are acceptable.
results of metallographic analysis
mechanical tests certificates, including single values
results and recording of NDT. A dedicated certificate for each performed NDT is required
dimensional report (tabular or graphically) complete of a certificate of compliance
